Punching bag



United States Patent PUNCHING BAG Claude James Helfner, Williamsport, Pa.

Application July 13, 1955, Serial No. 521,944

1 Claim. (Cl. 272-78) This invention relates to athletic bags of the striking and punching type for use in gymnasiums and it consists in the construction, arrangements and combinations herein described and claimed.

It is the cardinal object of the invention to provide a punch training bag in which the suspension straps for the bag are equally spaced around the outer periphery of the bag and extended vertically downward thereon for a major portion of the length of the bag affording greater supporting strength to the bag; the spaces between said straps representing the surface to be struck; and loops being of a folded character so as to project a substantial distance outwardly from the bag surface to thereby discourage striking the bag with the bare fists.

It is also a further object of the invention to provide a punching bag which may be manufactured at a low cost in miniature form, for home training use.

Additional objects, advantages and features of invention will be apparent from the following description, considered in conjunction with the accompanying drawing, wherein,

Figure 1 is a side elevation of the punching bag in suspended relation from a ceiling,

Figure 2 is a top plan View taken on the line 2-2 of Figure 1.

Figure 3 is a bottom view thereof, and

Figure 4 is an enlarged cross section taken on the line 4--4 of Figure 1.

There is illustrated a punching bag constructed from any suitable material such as canvas, preferably formed in a pair of sections 11 and 12 stitching the same longitudinally forming seams 13 and 14. One end of the bag is closed by a bottom wall 15. The opposite end of the bag is folded and stitched for reinforcing purposes and a plurality of circumferentially spaced eyelets 16 are formed inwardly of the open end of the bag for receiving a draw string 17, which when drawn taut will effect a secure closure for the bag.

Equally spaced circumferentially of the bag, there are four suspension straps 18 of identical construction, and as 2,826,416 Patented Mar. 11, 1958 may be seen in Figure 4, the straps are formed from a single strip of heavy material folded upon itself lengthwise to form a thickness and secured upon the bag by stitches 19.

As clearly shown in Figure 1, the straps at the upper free ends are formed as a loop 20 into which a ring 21 is secured, each ring having one end of a suspension chain 22 secured thereto, the other end of the chain being detachably engaged in a hook 23 fixed in the ceiling 24.

The straps 18 are of a length extending over the major portion of the length of the bag stopping short of the bottom 15.

The bag may be filled with sand, sawdust or other suitable material and the draw string 17 being drawn taut to close the open end of the bag. The chains 22 are then engaged with the book 23 for suspension of the bag, and obviously, the height of the bag may be adjusted by engaging proper links of the chain in the hook 23.

In use, the athlete will strike the bag only on the surface between the straps 18 and if any of the straps are struck, this will be considered as a foul. Also, by virtue of the thickness of the straps, a trainee will be discouraged from striking the bag with his bare fists, thus insuring the use of gloves.

From the foregoing, it will be seen that a strong support for the bag is provided by the use of the straps 18 and further that by the spacing of the straps as shown and described target areas are inherent on the bag, and while I have shown and described a preferred form of the device, this is by way of illustration, and I consider as my own all such modifications in construction as fairly fall within the scope of the appended claim.

A punching bag comprising a hollow cylindrical body formed from heavy flexible material having a single closed bottom wall, a pulverous material within the body, said body having a closure means for the upper open end of the bag, a plurality of straps circum'ferentially spaced and secured to the outer periphery of said body, said straps being formed from a single strip of heavy material folded lengthwise upon itself to provide a substantial thickness so as to project from the body, said straps being extended downwardly upon said body for the major portion of the length of the body and terminating above said closed bottom, the spaces between said straps forming target striking areas, said straps being extended above the upper end of said body and. terminating in a respective loop for reception of a suspension means for the bag.
